Anything can happen but, The Riv has taken them out of the cage. The destruction of chips process, takes some time in NV. Gaming asked that the Porn chips be removed. The Riv complied. IMO the only way more chips will surface is an employee theft before destruction.
The chips would be in a place with a name something like "Double Custody." The key would be in a secured locked box. The only key to the box, would be with security, and this key is in a secured lock box, that would have to be signed out by a security guard, at the direction of someone with authority to order it signed out.
Chips going for destruction at the Fiesta must be accompanied by a security guard, cage manager, and at least an assistant Controller. We use Bud Jones for destruction. BJ signs for the chips. Our 3 people watch the destruction. BJ signs that they are destroyed. The paper work goes to gaming.
Anything can happen, but!!!!!!
